Responsibility charting (RACI) is a technique used to clarify roles and responsibilities for activities and decisions within a process. It involves identifying the key activities and decisions, and then defining the participation of roles as either Responsible, Accountable, Consulted, or Informed. This provides clarity around individual responsibilities and accountability, reduces duplication of work, and improves communication and teamwork. The RACI process involves developing responsibility charts through workshops, documenting and communicating the charts, and follow up to ensure the defined roles are being followed. Benefits include increased productivity, reduced errors, streamlined structures, and better planning and training.
